FAsrENER-SETTING MACHINE.

Application filed April 26, 1918.

To all 'whom it may concern:

Be it known that I, PERLEY R. GLAss, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Fastener-Setting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to fastener inserting machines and particularly to machines organized for setting eyelets one at a time in various classes of work.

Eyeletting machines designed for setting eyelets in fiat work have almost universally been arranged so that the raceway delivered the eyelets to the lower set, the work being supported upon a flat table above this set. Eyelet machines are, however, extensively employed in setting eyelets one at a time in other classes of work, notably in pumps, rubber-soled shoes after they have been vulcanized, hats, caps, the cylindrical casings of electrical iiash lights, and, in general, in classes of work wherein it is desired to set the eyelet right side up and to deliver the eyelet to the upper set so that there will be no interference between the raceway and the work. The object of the present invention is to provide an improved machine especially designed to meet the requirements of such work, which machine shall be strong and reliable and inexpensive to manufacture.

Features of the invention consist in an improved organization for setting fasteners. These and other features of the invention will be best understood from a consideration of one particular embodiment thereof which will be described in the following specification in connection with the accompanying drawing, in which,-

steps in the operation of setting an eyelet; an

Fig. 7 is a vertical sectional view through the sets showing them in the position which they occupy at the end of the operation of setting an eyelet.

The illustrated machine is provided with a vertical frame 10 designed for attachment to a bench or table and having near its upper end a forwardly extending integral bracket 12 in which is slidably mounted a plunger 14 carrying a top set 16 which is provided with the usual spring pressed spindle 18. Co-

operating with the movable set 16 is a lowerl set or anvil 20 which is mounted in a forwardly extending arm 22 detachably connected to the frame of the machine and adapted to be variously designed to suit the particular class of work for which the machine is to be utilized.

Journaled in the upper part of the frame upon a horizontal axis is a drive shaft 24 arranged with outwardly extending ends, upon one of which there is mounted a driving pulley 26 and upon the other of which there is mounted a cam member 28. The driving pulley is preferably arranged to be connected to the shaft by means of suitable controlling mechanism such, for example, as a one revolution clutch adapted to be controlled by a foot pedal, neither of these parts being shown in the drawing.

Actuation of the plunger carrying the movable set 16 is effected by a yoke-shaped lever 30 which straddles a portion 32 of the frame, and which is connected to the latter by a fulcrum member 31., This mounting of the` Llever is sturdy and easily constructed and the bearing points are widely separated. A forwardly extending arm 34 of this lever is connected to the plunger 14 by means of parallel links 36 pivotally attached to a flattened portion of the upper end of the plunger and to a flange 38 upon the lower side of the lever arm 34. It will be noted that the forward end of the lever has been counterbored at 40 upon either side so that it overhangs the upper ends of the connecting links 36 and removes all strain from the pivot 42. rangement requires a minimum of machine work and nevertheless furnishes an accurate and very substantial construction so that the machine is enabled to deliver a strong blow It will be seen that such an arupon the top set 16. The rear arm 44 of the lever 80, formed as an extension of one side of the yoke, is actuated by means of a link or pitman 46 connected to a crank pin 48 carried by the cam member 28.

For the sake of symmetry, strength, and general efhciency the plunger 14 and the bearing for the shaft 24 are located in registration with the vertical median plane of the frame extending from front -to rear. Consequently the crank-pin 48 by which the plunger is actuated is removed a considerable distance from said median plane, its

remoteness from the plane being increased by the width of the cam member 28 that carries it. rllhis relation between the crank-pin and the plunger presents difhculties aifect ing the construction and mounting of the plunger-lever. The described construction affords the necessary strength and countern acts the tendency of the lever to tip or skew in a way that would cause it to bind or shift its ends out of line with the operating connection and the plunger connection respectively. The frame portion 32 on which the lever 30 is mounted extends substantially from the aforesaid median plane to a parallel plane in registration with the crank-pin, andthe lever 30, being formed to straddlev this portion of the frame, is provided with spaced hub portions 33 arranged one at either sine of the frame portion 32. The two arms 84 and 44 of the lever, being integral parts of the lever but offset laterally from each other a considerable distance because of the relation of the crank-pin to the plunger, are rigidly united without dependence upon the fulcrum member 31 to transmit motion from one arm to the other, the connecting portion of the lever by which the two arms are joined being a sufhcient distance from the axis to sustain the operating stresses without requiring excessively heavy or bulky construction.

Eyelets are supplied to the movable set 16 from an oscillatable raceway 50 provided with a hopper 52. The raceway and hopper are preferably assembled to move as one part, the raceway being pivotally connected to and between upstanding arms 54 of the bracket 12 by means of a manually removable pivot pin 56. The raceway receives fasteners in inverted position from the hopper 52, that to say with their flanges down, and delivers them right side up to the top set, that is to say with their flanges up. The usual spring-pressed retaining latch 58 is pivctally mounted upon the lower end of the raceway and retains the eyelets by engagement with the barrel of the lowermost eyelet. Oscillation of the raceway is effected by means of a rockshaft 60 journaled in the portions 32, 54 of the frame and having arms 62 and 64 with split hubs and bolts to clamp the arms adjustably upon the shaft.

It will be noted that the axis of the rockd shaft is perpendicular to the drive shaft 24 and parallel to the axis of the pivot 56. A roller 66 upon the arm 62 is arranged in a cam groove 68 in the periphery of the cam member 28. The arm 64 is connected to the raceway by means of a link 70 and a manually removable pivot pin 7 2. The novel construction thus provided affords the advantage that the movements of the raceway may be accurately controlled with respect to the movements of the top set by a proper design of the cam groove 68 to avoid interference between the two. It will be evident that the organization whereby the cam member 28 effects the actuation of the set actuating lever 80 and the rockshaft 60, while extremely efficient, is nevertheless a simple and inexpensive construction. Adjustment of the position of the end of the raceway with respect tothe top set is, as has already been intimated, provided for by loosening i one or the other of the arms 62, 64 upon the shaft and Vthen clamping it in adjusted position. Furthermore, the novel arrangement 0f the raceway with respect to its supporting pivot and its actuating mechanism enables the operative to change the raceway and hopper, when it is desired to use a different size or style of eyelet, by simply removing the pins 56 and 72 manually and without the use of any tool whatever.

Agitation of the eyelets in the hopper is effected by means of a rotatable brush 8O mounted upon a downwardly extending shaft 82 which passes through a boss upon the base of the hopper, and the rotation of this shaft 82 is effected by means of a driving pulley 86 connected to the main shaft 24 by means of a belt 88 passing over idlers 96. These idlers are pivotally mounted upon a bracket 92 detachably secured to the upstanding portion 32 of the frame. A driving pulley (not shown) for the belt 88 may, if desired, be constructed integrally with the cam member 28. The driving pulley 86 is retained upon the shaft 82 by means of a knob 94 pinnedto the lower end of the shaft. It may be seen from an inspection of Figs. 2 and 3 that the shaft 82 is notched at 96 to provide ratchet teeth which may be engaged by a spring pressed pin 98 in the hub of the pulley 86. By means of this construction, the operative is enabled at any time to rotate the brush to fill the raceway with fasteners by simply grasping the knob 94 and turning the agitator brush, and it will be seen that this may be done even though the machine is at a standstill and rotation of the pulley 86 either impracticable or impossible.

The operation of the machine as determined by the arrangement and timing of .the respective parts, is such that, starting from the stop position indicated in Fig. 4,

the lower end of the raceway is moved into alinement with the upper set 16 so that the lowermost eyelet therein will be threaded by the spindle 18 (see Fig. 5) and retained thereon by frictional engagement as the raceway withdraws and the upper set descends (see Fig. 6) until the eyelet is clenched upon the work 100 by the coperation of the upper set 16 with the lower set or anvil 20. From an inspection of Fig. 7 it will be noted that the upstanding projection at the center of the anvil 2O assists in the ready location of the punched work thereon and the guiding of the eyelet presented against the lower set and pushes the spindle 18 back into the top set in the usual fashion when the two sets come to clenching position.
